Two-piece wall plate for electrical device
First Claim
1. A two-piece wall plate for installation with at least one electrical wiring device having a body portion with an outer face of predetermined peripheral outline and a mounting strap with end portions extending outwardly in opposite directions from said body portion, each of said end portions having at least two openings therethrough, one for passage of a first screw securing said wiring device to a junction box and the other for receiving a screw attaching a portion of said wall plate to said wiring device, said wall plate comprising:
- a) a base plate comprising;
i) integrally formed top, bottom and side first frame portions collectively defining inner and outer faces and inside and outside boundaries of said base plate;
ii) a bezel extending outwardly from said base plate outer face about substantially the entire periphery of said base plate inside boundary, and having a top surface and inwardly and outwardly facing side surfaces, said inwardly facing side surface defining a first opening of substantially the same configuration and dimensions as said predetermined outline;
iii) a second and a third opening in each of said top and bottom frame portions;
b) a cover plate comprising;
i) integrally formed top, bottom and side second frame portions collectively defining inner and outer faces and inside and outside boundaries of said cover plate;
ii) a first lip portion extending outwardly from said cover plate inner face about substantially the entire periphery of said cover plate outside boundary, said first lip portion having an inner boundary encompassing said base plate outer boundary;
iii) said inside boundary of said second frame portion defining a fourth opening of substantially the same configuration and dimensions as said outwardly facing wall of said bezel; and
c) cooperative, first and second engagement means on said bezel outwardly facing side surface and said second frame portion inside boundary, respectively, for releasably retaining said base and cover plates in mutually engaged relation with said bezel extending through said fourth opening.

Abstract
A two-piece wall plate for use with a wall mounted receptacle, switch or other wiring device. A first, frame-like base plate is secured by screws to the mounting ears of the wiring device, and a second, frame-like cover plate is releasably connected to the base plate, in covering relation thereto. A bezel portion of the base plate closely surrounds the periphery of one or more wiring devices mounted in the usual way in a conventional wall box, and extends through a central opening in the cover plate. The cover plate is mounted on the base plate by a snap fit connection provided by elongated grooves in the outwardly facing side surface of the bezel which receive elongated ridges extending inwardly about the boundary of the central opening in the cover plate.

7. A wall plate assembly for attachment to a wiring device installed in the open front of a junction box mounted behind an opening in a building wall, said wiring device including a body portion and a mounting strap and being secured to said junction box by a first pair of mounting screws passing loosely through respective openings in said mounting strap, said assembly comprising:
-
a) a base plate comprising a first, frame-like member having an outer periphery larger than the outer periphery of said wall opening and an inner periphery adapted to closely surround an exposed surface of said wiring device, said base plate and wiring device cooperatively entirely covering said open front of said wall box when assembled therein, b) a cover plate comprising a second, frame-like member having an outer periphery larger than the outer periphery of said base plate, and an inner periphery closely surrounding an exposed surface of said base plate; c) cooperative snap-fit connection means including a first portion on said base plate and a second portion on said cover plate for releasable connection of said cover plate to said base plate; and d) screw means for securing said base plate to said mounting strap, said screw means being concealed by said cover plate when the latter is connected to said base plate. - View Dependent Claims (8, 9, 10, 11)
